Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584262, here are decompositions:

29 + 31584233 = 31584262
71 + 31584191 = 31584262
89 + 31584173 = 31584262
263 + 31583999 = 31584262
431 + 31583831 = 31584262
443 + 31583819 = 31584262
491 + 31583771 = 31584262
509 + 31583753 = 31584262

Showing the first eight; more decompositions exist.
